Addressing Public Mental Health Challenges: A Mixed-Methods Evaluation of Problem-Based Learning

Problem-based learning (PBL) is a pedagogical framework that centers on a problem of interest and structures classroom tasks around teams formulating practical, evidence-based solutions. This approach is particularly well-suited for public health curricula, as it prepares students for a dynamic, interdisciplinary, professional environment. This study explores the piloting of a PBL approach with three student cohorts in a graduate-level public mental health course. Biweekly, interdisciplinary student teams were presented with a public mental health case provided by an expert in the field and asked to develop and present evidence-based solutions through a process grounded in knowledge acquisition, critical thinking, and faculty guidance. A mixed-methods evaluation was completed to examine student perceptions of PBL components and the benefits of PBL and to gather recommendations to enhance this approach. Among 37 students who completed self-administered surveys, more than 70% found case analysis, reviewing additional literature to support case solutions, and discussions with an expert to be the components "Most Helpful" to their learning. Four focus groups with 21 students were conducted to further examine perceived course benefits and suggested changes. Participants appreciated real-world simulations of public health issues and interdisciplinary teams and offered recommendations for future improvements, such as adding a culminating project. Findings support the benefits of a PBL approach in equipping graduate students with the knowledge and skills to successfully pursue professional public health work. Recommendations inform future efforts to implement this approach in other public health curricula as well as for other courses and settings.
